DARPA's latest: a wrap that stops bleeding with sound
If we had our way, all our military tax dollars would go to DARPA. Whether it be nano planes, robot arms, or high-resolution sniper scopes, it always has something interesting cooking, and today's defense-minded gadget is no different. It's called a DBAC device, for Deep Bleeder Acoustic Coagulation; basically a portable ultrasound wrap that can identify wounds ("bleeders") and reduce their severity. It uses Doppler waves to find an internal leak, then turns up the frequency and amplitude on that location to stem it, all in a completely automated fashion able to be managed by any Joe in a hot zone. Okay, so perhaps it's not as cool as a remote-controlled zombie shark, but this cuff has the potential to save many lives and limbs on the battlefield -- assuming it works. DARPA hopes to have a functional prototype ready in 18 months. [Warning: PDF read link]
